GLASS-'HOLDING DEVICE FOR METALLIC WINDOWS.

Specification of Letters Patent.

Application filed April 24, 1913. Serial No. 763,350.

T0 all whom it may concern.'

Be it known that I, ROBERT S. DRUMMOND, a citizen of the Uni-ted States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Glass- It is therefore frequently required that the glass panes should be secured by metallic flanges or strips. On the other hand, the putty joint-such as used upon wooden window sashes-is more thoroughly weather proof than the metallic constructions, and` the present invention is designed to combine in a single structure the advantages of the metallic securing means and the putty joint. In the drawings: Fi 1e 1 is a front elevation of a portion o a metallic securing device forvthe glass; Figs. 2 and 3 are respectively side and front elevations of the metallic securin strips detached; and Fig. 4 is an enlarge cross section showing the glglss secured -and weather-proofed in the sa f A is a metallic window sash of an suitable construction, being preferably ormed of intersecting T-head bars B having stem portions C.

D is the glass ane which is seated against the inner face o the T-head B with its edge adjacent to the stem portion C.

E is a metallic fastening device, preferably in the form of an angle bar having one flange E lying adjacent to the stem C and detachably secured thereto by suitable means, such as the bolts I".

To weather-proof the joint, the glass pane is embedded in putty, which lies between the edge thereof and the stem C and also between the shoulder on the head B and the adjacent edge of the lass. To further insure the weather-proo g, the bar E is provided on the flange which lies adjacent to the glass with an outwardlyeXtending obliquely-bent portion E2. This forms an angular recess in which putty may be placed, las indicated at G, and by reason of the tapering form there will be no opening of the joint through shrinkage.

The construction as described forms a more -thoroughly weather-proofed j oint than can be obtained by metallic fastenings; while, on the other hand, the glass is securely held by the metallic parts alone and does not in any way depend upon the putty.

What I claim as my invention is:

The combination with a metallic window sash provided with a seat, and a retaining strip secured thereto, of a pane of glass engaged between said stri and saidseat, the body portion of the strip being in contact with theadjacent face of the glass and its edge portion being flared forming a putty recess between the glass and retaining strip. i In testimony whereof I aiix my signature in presence of two witnesses.

ROBERT S. DR OND.
